The prison ministry is the centerpiece of Sabbath Keepers Fellowship and is the focus of its charitable operations. As well as worship services, the ministry provides books, bibles, concordances, calendars, our Freedom's Call newsletter, teachings and articles, various worship items such as the tallith (prayer shawl), kippah, women's head-coverings, Passover packages, as well as holyday and Sabbath matzah (bread) and juice, to prison inmates and to their families. As a personal outreach, the ministry members provide personal correspondence to inmates promoting biblical values and ideals, as well as a Pen-Pal program that connects inmates with suitable, like-minded pen-pals.
